The CRU graph. Note that it is calibrated in tenths of a degree Celsius and that even that tiny amount of warming started long before the late 20th century. The horizontal line is totally arbitrary, just a visual trick. The whole graph would be a horizontal line if it were calibrated in whole degrees -- thus showing ZERO warming

Warmists jittery about Berkeley project

They say that the Muller team findings will make "no difference" to the temperature record but are clearly critical nonetheless. They are so defensive that now they even say that thermometer readings are irrelevant! -- LOL!

An effort by a handful of UC Berkeley scientists to reexamine temperature data underlying global warming research has landed in the center of a national political debate over government regulation.

The Berkeley Earth Surface Temperature study is led by physicist Richard Muller, a longtime critic of the scientific consensus on climate change, who plans to testify on the effort Thursday before the House Science Committee in the latest of several congressional inquiries on climate science since the GOP majority was seated.

The Berkeley project's biggest private backer, with $150,000, is the Charles G. Koch Charitable Foundation. Oil billionaires Charles and David Koch are the nation's most prominent funders of efforts to prevent curbs on fossil-fuel burning, the biggest contributor to planet-warming greenhouse gases.

Temperature data from tens of thousands of weather stations across the globe, many of which have incomplete records, are "very contentious," Muller said in an interview. "The skeptics are raising legitimate concerns."

Leading climate scientists, however, say the three most in-depth temperature studies agree on the overall severity and pace of global warming. They worry that the Berkeley effort, and the hearing Thursday, will add to public confusion on a topic that is as politically polarized as it is scientifically complex.

Muller said Koch and other contributors will have no influence over the results. "We have no prejudice, no preconception of what we are going to get," he said, adding that the Koch donation was less than the $188,587 contributed by the federal Lawrence Berkeley National Laboratory, where Muller is a senior scientist.

"Global warming is a serious problem," Muller said in a lecture at UC Berkeley last week. "But people simply don't believe the story anymore because the story was exaggerated.... Not a single polar bear has died because of receding ice."

The Berkeley study comes as efforts to curb planet-heating emissions from industrial plants and motor vehicles are under attack in Congress. The Supreme Court in 2007 said the Environmental Protection Agency could regulate greenhouse gases under the Clean Air Act, but Republicans and coal-state Democrats, citing uncertainty over the science, are sponsoring legislation to thwart that effort.

Temperature data were the focus of the so-called 2009 Climategate controversy, in which opponents of greenhouse gas regulation alleged that leaked emails from a British climate laboratory showed manipulation of weather station records. Five U.S. and British government and university investigations have refuted the charges.

The Berkeley effort is hardly new. Over the last two decades, three independent scientific groups have analyzed international data from thousands of weather stations. Using different combinations of stations and varying statistical methods, all have come to nearly identical conclusions: The planet's surface, on average, has warmed about 0.75 degrees centigrade (1.4 degrees Fahrenheit) since the beginning of the 20th century.

Scientists involved in those studies said they would welcome new peer-reviewed research, but they contend that Muller is violating scientific protocol by publicizing his project, underway for months, before it produces any vetted scientific papers.

"I am highly skeptical of the hype and claims," said Kevin Trenberth, who heads the Climate Analysis Section of the National Center for Atmospheric Research, a university consortium. "The team has some good people but not the expertise required in certain areas, and purely statistical approaches are naive. I suspect they have an agenda."

The Koch donation, to many, confirms those suspicions. "Why would a scientist accept funding from an organization with no interest in advancing the science?" asked Benjamin Santer, an atmospheric scientist at Lawrence Livermore National Laboratory.

Muller said his team would submit to peer-reviewed journals data that "measure the warming with more precision than in the past." He acknowledged that his study could find that issues raised by skeptics have only a "marginal effect" on temperature estimates. "Don't expect any huge surprises," he warned. "The surprises may be in the fine tuning."

Muller and many of those who question the temperature data are drawn to the "urban heat island" phenomenon, maintaining that gauges may be registering latent heat from asphalt, concrete and other urban features. Over time, some weather stations that once recorded temperatures in rural areas have been surrounded by cities and suburbs.

The Berkeley project is analyzing information from 39,000 stations —five times as many as the other groups, Muller said — and will address the fact that temperature data have been recorded at varying times of day.

The project also will put its calculations on the Internet in a "transparent" way, Muller said. Other scientists, he said, "put homogenized data online. They don't put up the [software] tools that get you from the raw data to the homogenized data. How do they pick the [weather station] sites? That involves human judgment."

Peter Thorne, a leading expert on temperature data at the National Oceanic and Atmospheric Administration's National Climatic Data Center in Asheville, N.C., said the three main data sets by the NOAA, NASA and Britain's Hadley Centre adjust for the heat island effect, as well as for measurements at different times of day. Muller's use of 39,000 weather stations, he said, "will make next to no difference" in the final result.

Thorne said the data and computer code for the NASA analysis have been publicly online for five years, while NOAA's data and code have been online for three years. Most of the British center's data are online, except for information shared on a confidential basis by commercial groups, and the code is available, he said.

Thorne said he was unsurprised by the Berkeley project's focus on temperature data. "For those who wish to discredit the science, this record is the holy grail," he said. "They figure if they can discredit this, then society would have significant doubts about all of climate science."

But temperature is only one indicator of global warming, Thorne said. "Even if the thermometer had never been invented, the evidence is there from deep ocean changes, from receding glaciers, from rising sea levels and receding sea ice and spring snow cover. All the physical indicators are consistent with a warming world. "There is no doubt the trend of temperature is upwards since the early 20th century. And that trend is accelerating."

Some cheerful news on the climate change front today, as US government boffins report that ice breaking off the Antarctic shelves and melting in the sea causes carbon dioxide to be removed from the environment. This powerful, previously unknown "negative feedback" would seem likely to revise forecasts of future global warming significantly downwards.

The US National Science Foundation (NSF) which funded the iceberg study, describes the results as having "global implications for climate research".

A team of NSF-funded scientists examined the effects on an area of the Weddell Sea of a large (20 mile long) berg moving through, melting as it went and diluting the salty sea water - also adding key nutrients carried from the land. They found that after the iceberg had passed, levels of CO2 had plunged and much more chlorophyll was present. Chlorophyll is the substance in green plants which lets them suck in nasty CO2 and emit precious life-giving oxygen: in the Weddell Sea it was present in phytoplankton, tiny seagoing plantoids which are thought to account for half the carbon removed from the atmosphere globally.

The scientists say that more and more icebergs are set to be found in the seas around the Anatarctic as more ice breaks off the shelves attached to the peninsula which reaches up from the polar continent towards South America. This should mean more phytoplankton and thus less CO2.

The iceberg team consider that the increased number of bergs coming from the western Antarctic is the result of warming temperatures in the region, though recent research from British boffins has suggested that in fact other factors may be in play - at least in the case of the Pine Island Glacier, one of the major sources of sea ice in that area.

If the phytoplankton-boosting effect of the bergs is as big as the NSF appears to be suggesting, however, it would seem that any carbon-driven temperature rise could be at least partly self-correcting.

Increased iceberg shedding would seem likely to be seen mainly or only around the western peninsula: antarctic sea ice shelves elsewhere are actually growing, not shrinking, and at such a rate as to outweigh the peninsular losses. The past three decades have seen the south-polar ice sheets grow by 300,000 square kilometres overall.

The NSF study was originally published in the journal Deep Sea Research Part II (subscription required). It was flagged up more recently in Nature Geoscience's top picks (again, subscription link). The NSF also has a statement here.

On the heels of the pronouncement by one of the gurus of global warming that any decrease in the earth’s temperature could be a thousand years away, another scientist has stepped forward with the warning that a new Ice Age could be right around the corner.

Professor Tim Flannery, the head of Australia’s Climate Change Commission, sparked the latest scandal in the global warming community when he recently declared, "If the world as a whole cut all emissions tomorrow, the average temperature of the planet's not going to drop for several hundred years, perhaps over 1000 years."

As reported previously for The New American, Prof. Flannery has endeavored to ameliorate the effects of his comment by claiming that temperatures would begin to drop by the end of the century, but his millenarian prognostications served to highlight the ineffectiveness — even insignificance — of the proposed draconian reductions in the world’s industrial activity.

However, if George Kukla is correct, the cooling which Flannery and his cohorts desire may be coming in spades. Kukla, a retired professor of paleoclimatology at Columbia University, believes the Earth is no overdue for an Ice Age. An article by Terrence Aym (“Prepare for new Ice Age now says top paleoclimatologist”) at Helium.com sets forth some of Kukla’s argument:

The "Earth has experienced an ongoing cycle of ice ages dating back millions of years. Cold, glacial periods affecting the polar to mid-latitudes persist for about 100,000 years, punctuated by briefer, warmer periods called interglacials," Kukla says.

Co-author of an important section of the book "Natural Climate Variability on Decade to Century Time Scales," Kukla asserts all Ice Ages strat [sic] with a period of global warming. They are the the harbingers of new Ice Ages. Actually, he explains, warming is good. Ice Ages are deadly and may even kill millions.

Can Mankind stop it? No. Just as humanity cannot affect the long term climate of the planet, neither can it stop an Ice Age from happening. The climate is primarly [sic] driven by the sun.

Kukla has been warning of the possibility of new Ice Age for some time, and the cycle which he and other scientists believe may drive the process of climate change has been observed since at least the 1920s. Eleven years ago, Kukla gave a brief summary of his view on the cause of climate change for an article published by the Columbia University News:

In fact, the geologic record reveals that Earth has experienced an ongoing cycle of ice ages dating back millions of years. Cold, glacial periods affecting the polar to mid-latitudes persist for about 100,000 years, punctuated by briefer, warmer periods called interglacials. The Holocene is just another interglacial that is more than half over, Kukla said.

It turns out that this ongoing cycle of glaciation closely matches cyclic variations in Earth's orbit around the sun, leading many researchers to conclude that orbit drives glaciation. This correspondence between orbit and climate is called the Milankovich cycle, after the scientist who analyzed and popularized it in the 1920s.

"I feel we're on pretty solid ground in interpreting orbit around the sun as the primary driving force behind ice-age glaciation. The relationship is just too clear and consistent to allow reasonable doubt," Kukla said. "It's either that, or climate drives orbit, and that just doesn't make sense."

Kukla claims that 116,000 years have passed since the last Ice Age; therefore, if the theory is correct, Earth would be overdue for global cooling.

Of course, Kukla is not the only advocate of a theory of a new Ice Age; the difference between him and some very prominent promoters of the theory is that his model does not recognize any connection between such an event and human activity. Obama’s science ‘czar,’ John Holdren, coauthored a book with Paul Ehrlich in 1971 predicting that “global over-population was heading the Earth to a new ice age unless the government mandated urgent measures to control population, including the possibility of involuntary birth control measures such as forced sterilization.” Now, the doom and gloom crowd have completely reversed their assessment of the disaster which they claim will soon befall the human race, but the “solution” remains the same: Devastate the human species.

As the global warming theory has withered under public scrutiny in the aftermath of the Climategate and Glaciergate scandals, the theory’s proponents have been dashing around looking for a way to push their agenda. Last year, Holdren tried to adjust the language of the climate change debate by promoting a new terminology of “global climate disruption.” The cultivated ambiguity of Holdren’s new phraseology permits virtually any anomalous weather activity to constitute “proof” of their theory—rendering the theory incapable of being falsified, which is usually a fine indicator of pseudoscience.

Thus, Kukla’s theory of a new Ice Age is utterly different from the Holdren/Ehrlich’s “new Ice Age” of the 1970s, or the “global warming” scare which has predominated in the circles of scientific apocalypticism in recent decades. If Kukla is right, the Ice Age will come according to its own schedule, and there’s nothing that the human race can do about it—except, of course, for enjoying the brief warming that precedes the big chill.

The guys below are tree ring experts and even though they are Warmists, they have to admit how difficult it is to draw any firm conclusions from such data

Tree rings are a good place to start thinking about how climate researchers get information about past climates. In certain cases, trees can live for many hundreds of years and in an extraordinary case, like the bristlecone pine, thousands of years! Each year trees add growth rings, which can indicate what sort of growing season the tree experienced. Interestingly these rings are more than a temperature indicator, they also tell the researcher about moisture and cloudiness as well.

Dendrochronology is the study of climate change as recorded by tree growth rings. Each year, trees add a layer of growth between the older wood and the bark. This layer, or ring as seen in cross section, can be wide, recording a wet season, or narrow, recording a dry growing season. Because the rings are basically recording a good growing season or a bad growing season, they are indirectly recording more than just moisture. They also document temperature and cloud cover as they impact tree growth as well. This record of annual summer information is very important when you consider that certain types of trees grow slowly over hundreds and hundreds of years, and therefore contain a record of as many years of climate and climate change.

There are limitations to this research though. Trees in the temperate zone only record the growing season, so the winter season, no matter how dramatic, will not be seen in the ring record. Interestingly, trees in tropical regions grow year round and therefore show no real obvious annual growth rings. Therefore climate data from equatorial areas is difficult to piece out and use. The record is limited geographically in another way too. Trees do not grow in all places on Earth, therefore we don’t have a tree ring record of climate change for each region and ecologic niche globally. (No trees in polar regions, high in the mountains, in the ocean!!!)

In order to know more about climate over an even longer period of time, in some cases thousands of years, it is possible to look at dead trees of an unknown age that are still well preserved. One can correlate their rings to the rings of a living tree (whose age you know), and get a longer record of climate through time. An amazing example of this is the tree ring chronologies established by looking at bristlecone pines through time. Not only are bristlecone pines the longest lived trees on earth, they also live in a place where, even when they do die, they are well preserved over hundreds or thousands of years. We can therefore look at a living bristlecone, take its ring record , then look at a dead tree and see where the rings match up. In this way, scientists have established a ring record that records climate signals for over 9,000 years into the past.

Dendrochronology is currently still in its scientific infancy – there are many problems in the use of tree rings, particularly because the growth of tree rings can be impacted by many issues - not just rainfall amount, temperature, and cloud cover – but also by wind, soil properties, disease, or even pollution. These issues can certainly impact tree ring growth and cloud the scientific record. Fortunately, scientists are gaining new insight in the reading and use of tree rings, and hope that they can be used to help understand whether global warming has any precedent in the ring record of the past 1,000 years.

“The Montreal Protocol to ban freons was the warm-up exercise for the IPCC. Many current IPCC players gained fame then by stampeding the US Congress into supporting the Montreal Protocol. They learned to use dramatized, phony scientific claims like “ozone holes over Kennebunkport” (President Bush Sr’s seaside residence in New England). The ozone crusade also had business opportunities for firms like Dupont to market proprietary “ozone-friendly” refrigerants at much better prices than the conventional (and more easily used) freons that had long-since lost patent protection and were not a cheap commodity with little profit potential” (link).

Even James Lovelock agrees. James Lovelock formulated the Gaia hypothesis, which postulates that the biosphere is a self-regulating entity with the capacity to keep our planet healthy by controlling the chemical and physical environment. He later became concerned that global warming would upset the balance and leave only the arctic as habitable. He began to move off this position in 2007 suggesting that the Earth itself is in “no danger” because it would stabilize in a new state.

James Lovelock’s reaction to first reading about the leaked CRU emails in late 2009 was one of a true scientist.

“I was utterly disgusted. My second thought was that it was inevitable. It was bound to happen. Science, not so very long ago, pre-1960s, was largely vocational. Back when I was young, I didn’t want to do anything else other than be a scientist. They’re not like that nowadays. They don’t give a damn. They go to these massive, mass-produced universities and churn them out. They say: “Science is a good career. You can get a job for life doing government work.” That’s no way to do science.

I have seen this happen before, of course. We should have been warned by the CFC/ozone affair because the corruption of science in that was so bad that something like 80% of the measurements being made during that time were either faked, or incompetently done.

Fudging the data in any way whatsoever is quite literally a sin against the holy ghost of science. I’m not religious, but I put it that way because I feel so strongly. It’s the one thing you do not ever do. You’ve got to have standards.”

On a March 2010 Guardian interview, Lovelock opined

“The great climate science centres around the world are more than well aware how weak their science is. If you talk to them privately they’re scared stiff of the fact that they don’t really know what the clouds and the aerosols are doing...We do need skepticism about the predictions about what will happen to the climate in 50 years, or whatever. It’s almost naive, scientifically speaking, to think we can give relatively accurate predictions for future climate. There are so many unknowns that it’s wrong to do it.”

Will Happer further elaborated

“The Montreal Protocol may not have been necessary to save the ozone, but it had limited economic damage. It has caused much more damage in the way it has corrupted science. It showed how quickly a scientist or activist can gain fame and fortune by purporting to save planet earth. We have the same situation with CO2 now, but CO2 is completely natural, unlike freons. Planet earth is quite happy to have lots more CO2 than current values, as the geological record clearly shows. If the jihad against CO2 succeeds, there will be enormous economic damage, and even worse consequences for human liberty at the hands of the successful jihadists.”

LIKE GLOBAL WARMING THE DATA DOESN’T SUPPORT THE THEORY

The ozone hole has not closed off after we banned CFCs. See this story in Nature about how the Consensus about the Ozone Hole and Man’s Role (with CFCs) May Be Falling Apart.

The size of the hole has hardly changed since 1990

“As the world marks 20 years since the introduction of the Montreal Protocol to protect the ozone layer, Nature has learned of experimental data that threaten to shatter established theories of ozone chemistry. If the data are right, scientists will have to rethink their understanding of how ozone holes are formed and how that relates to climate change. Markus Rex, an atmosphere scientist at the Alfred Wegener Institute of Polar and Marine Research in Potsdam, Germany, did a double-take when he saw new data for the break-down rate of a crucial molecule, dichlorine peroxide (Cl2O2). The rate of photolysis (light-activated splitting) of this molecule reported by chemists at NASA’s Jet Propulsion Laboratory in Pasadena, California1, was extremely low in the wavelengths available in the stratosphere - almost an order of magnitude lower than the currently accepted rate.

“This must have far-reaching consequences,” Rex says. “If the measurements are correct we can basically no longer say we understand how ozone holes come into being.” What effect the results have on projections of the speed or extent of ozone depletion remains unclear.

Other groups have yet to confirm the new photolysis rate, but the conundrum is already causing much debate and uncertainty in the ozone research community. “Our understanding of chloride chemistry has really been blown apart,” says John Crowley, an ozone researcher at the Max Planck Institute of Chemistry in Mainz, Germany. “Until recently everything looked like it fitted nicely,” agrees Neil Harris, an atmosphere scientist who heads the European Ozone Research Coordinating Unit at the University of Cambridge, UK. “Now suddenly it’s like a plank has been pulled out of a bridge.”

STILL COMING

Yet like the cultists whose spacecraft didn’t arrive on the announced date, the government scientists find ways to postpone it and save their reputations (examples “Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a Johns Hopkins earth scientist suggests” here and “Scientists Find Antarctic Ozone Hole to Recover Later than Expected” here.

“The warmers are getting more and more like those traditional predictors of the end of the world who, when the event fails to happen on the due date, announce an error in their calculations and a new date.”

How big an effect on world temperature will Australia's proposed carbon tax have?

Lord Monckton has been kind enough to give me the straight answer that Flannery et al will not - and his answer explains exactly Flannery's embarrassed silence:

Q. What is the central estimate of the anthropogenic global warming, in Celsius degrees, that would be forestalled by 2020 if a) Australia alone and b) the whole world cut carbon emissions stepwise until by 2020 they were 5% below today's emissions?

Answer a). Australia accounts for (at most) 1.5% of global carbon emissions. A stepwise 5% cut by 2020 is an average 2.5% cut from now till then. CO2 concentration by 2020, taking the IPCC's A2 scenario, will be 412 parts per million by volume, compared with 390 ppmv now. So Man will have added 22 ppmv by 2020, without any cuts in emissions. The CO2 concentration increase forestalled by almost a decade of cap-and-tax in Australia would thus be 2.5% of 1.5% of 22 ppmv, or 0.00825 ppmv. So in 2020 CO2 concentration would be 411.99175 ppmv instead of 412 ppmv.

So the proportionate change in CO2 concentration if the Commission and Ms. Gillard got their way would be 411.99175/412, or 0.99997998. The IPCC says warming or cooling, in Celsius degrees, is 3.7-5.7 times the logarithm of the proportionate change: central estimate 4.7. Also, it expects only 57% of manmade warming to occur by 2100: the rest would happen slowly and harmlessly over perhaps 1000 years (that's the real meaning of Flannery's 1000-year point, and it doesn't do him any favours).

So the warming forestalled by cutting Australia's emissions would be 57% of 4.7 times the logarithm of 0.99997998: that is - wait for it, wait for it - a dizzying 0.00005 Celsius, or around one-twenty-thousandth of a Celsius degree. Your estimate of a thousandth of a degree was a 20-fold exaggeration - not that Flannery was ever going to tell you that, of course.

Answer b) . Mutatis mutandis, we do the same calculation for the whole world, thus:

2.5% of 22 ppmv = 0.55 ppmv. Warming forestalled by 2020 = 0.57 x 4.7 ln[(412-0.55)/412] < 0.004 Celsius, or less than four one-thousandths of a Celsius degree, or around one-two-hundred-and-eightieth of a Celsius degree. And that at a cost of trillions. Whom the gods would destroy .

If you'd like chapter and verse from the IPCC's documents and from the peer-reviewed for every step of this calculation, which takes full account of and distils down the various complexities and probabilities Flannery flannelled about, you'll find it in this paper.

A cautionary note: the warming forestalled will only be this big if the IPCC's central estimate of the rate at which adding CO2 to the atmosphere causes warming is correct. However, it's at least a twofold exaggeration and probably more like fourfold. So divide both the above answers by, say, 3 to get what will still probably be an overestimate of the warming forestalled.

EVERY Australian family should be limited to just two children to curb the population explosion, controversial millionaire Dick Smith says. He called for a China-like quota on the number of kids, warning the growing burden on our resources was like "a plague of locusts".

Likening high-rise apartments to chicken coops, the former Australian of the Year thanked property developers at an Urban Taskforce population debate in Sydney for "not lynching" him after he attacked their drive for profits and called for an end to the growth addiction.

"It's either going to be forced on us or we are going to plan to stabilise," Mr Smith said. "I would like to see Australia stabilise at 24 to 25 million. I don't see it by force I see it by saying to parents, it's best to have two kids. I see us having an immigration intake of 70,000 per year."

Unaffordable land prices left generations of children stuck in apartments, he said. "We descended from hunter gatherers - not from termites," Mr Smith said. "We are putting our kids into high-rise because we are running out of land, because people want and need to live close to the city. We pay $50 million a year for free range eggs for our bloody chooks to be free range - what about our kids? I was a free range kid. I had a backyard. We are starting to lose that now, and it's only driven by the huge population increases."

Population growth had to slow to allow housing to become affordable again, he said, warning bad handling could lead to a recession.

Mr Smith called for an end to "stealing resources" from future generations. "We have to decide - are we like locusts that breed to huge numbers and then die off? Or are we like the majority of other magnificent natural creatures in this country which have lived in balance for millions of years?" he said.

" We have to decide we're going to live in balance or breed up and die off. There are people who say we will get to 9.1 billion and one enormous catastrophe will wipe out most of the people and if that's going to happen enjoy the advantages now. That might not happen."

Mr Smith said the economic system was built on "perpetual exponential growth". "We are completely addicted to growth. It's like the religion of capitalism but it is a false God," he said

MacroPlan economist Brian Haratsis called Mr Smith alarmist and "using scare tactics" He said population debate in Australia had been stolen by "anti-growth people with a Green sentiment". "We can triple the population of Australia if we want to and we wouldn't use much land. You only have to jump in a plane to Sydney and fly to Perth and what do you see? Not much."

Mr Haratsis said a population of 40 million was inevitable and that "the only choice is if we want a really big Australia of 40 million to 80 million".

I HAVE a brilliant idea for water management in Australia. What this dry continent needs is a way of storing and reticulating water to vast numbers of people in cities. I have come up with an invention that I call a "dam".

Let's build these "dams" outside each major city so that water might be stored and drawn down upon when needed. It's so simple and so cheap I cannot believe that no one in government or the bureaucracy has thought of it before. It sure would save a lot of money.

There are by my count six desalination plants either recently completed or under construction in Australia.

These things can cost in excess of $5 billion plus financing and operating costs. A "dam" on the other hand can store and deliver vastly more water at a cost of say $2bn. There, I've just saved the taxpayer $3bn and that's on a single project.

Of course, my idea for a "dam" is not new; I have nicked it from history. The last dam built to supply Sydney was the Tallowa completed in 1976 when the metropolitan population was 3.1 million.

Some 35 years later Sydney's population has expanded by 1.5 million, or 48 per cent, and there's no plan to add another dam for at least another decade, if ever.

This is extremely odd. I do not recall a conversation let alone a furious public debate about the management of Sydney's, or any other major Australian city's, water future.

At what point over the last three decades was a decision made that no new dams should be built and that future water supplies should be based on more expensive options such as desalination plants and/or pipelines?

Other cities are in much the same position: Melbourne has added 1.2 million since the completion of the Thomson Dam in 1984 and Brisbane has added 1 million since the Wivenhoe was completed also in 1984.

I have never understood the anti-dam lobby's argument that "why build a dam when it will never fill?" So, if this was the case and we had two dams both at 20 per cent capacity then doesn't this deliver twice the water security of one dam at 20 per cent?

I do understand that the construction of a dam will have a detrimental environmental impact. But environmental impact statements articulate the negatives. They never properly account for the positives associated with a dam.

And, yes, there are positives. More water for an urban population allows householders to develop gardens which attract birdlife and contribute more generally to what environmentalists call "the urban forest". I'm all for urban forests -- let's deliver the water these forests need to flourish and in so doing deliver quality of life to millions.

Do environmental impact statements incorporate the health costs of old people struggling with "bucket back" caused by watering restrictions? What about the psychological impact on those who fret about not having enough water for their gardens? No, not relevant?

Another dam has not been built in Brisbane's Lockyer Valley since the Wivenhoe which in turn was partially a flood mitigation device following the 1974 floods. How much water would have been retained by a second dam had it been built in say the late 1990s or early 2000s? What degree of calamity might have been averted by the existence of such a dam?

Surely flood mitigation is a positive impact of a dam. And what is the response of those whose influential water reports of the 1990s and the 2000s argued that we cannot rely on regular rainfall in the future to fill dams? Do these experts now concede that they got it wrong? If you got it wrong then why should we rely on your advice that we should not build dams in the future?

I might add that my argument in support of dams is not entirely in the interests of the property industry. Which do you think the property industry would prefer if it was purely self-interested: a desalination plant costing $5bn or a dam at $2bn?

The Australian people are indebted to the anti-dam lobby for forcing behavioural change with regard to water usage over the past 30 years: we have evolved a long way from water profligacy. But there comes a point in a city's growth when practical and hard-headed decisions need to be taken.

We haven't built a dam to service Sydney, Melbourne or Brisbane for a generation. We've had a dam-building hiatus and we've moderated our water usage, now it's time to build cost-efficient dams.

Or at the very least let's have a conversation about the subject rather than allowing various levels of government to solely pursue less efficient and more expensive alternatives such as pipelines and desalination plants.

There may well be a place for these "insurances" against another decade-long drought in the future, but we also need to be considering dams as a way of delivering baseload water supplies for our biggest cities in the 21st century.

Background

Context for the minute average temperature change recorded: At any given time surface air temperatures around the world range over about 100°C. Even in the same place they can vary by nearly that much seasonally and as much as 30°C or more in a day. A minute rise in average temperature in that context is trivial if it is not meaningless altogether. Scientists are Warmists for the money it brings in, not because of the facts

This site is in favour of things that ARE good for the environment. That the usual Greenie causes are good for the environment is however disputed. Greenie policies can in fact be actively bad for the environment -- as with biofuels, for instance

And when it comes to "climate change", I know where the skeletons are buried

Warmists depend heavily on ice cores for their figures about the atmosphere of the past. But measuring the deep past through ice cores is a very shaky enterprise, which almost certainly takes insufficient account of compression effects. The apparently stable CO2 level of 280ppm during the Holocene could in fact be entirely an artifact of compression at the deeper levels of the ice cores. . Perhaps the gas content of an ice layer approaches a low asymptote under pressure. Dr Zbigniew Jaworowski's criticisms of the assumed reliability of ice core measurements are of course well known. And he studied them for over 30 years.

The world's first "Green" party was the Nazi party -- and Greenies are just as Fascist today in their endeavours to dictate to us all and in their attempts to suppress dissent from their claims.

Was Pope Urban VIII the first Warmist? Below we see him refusing to look through Galileo's telescope. People tend to refuse to consider evidence— if what they might discover contradicts what they believe.

Warmism is a powerful religion that aims to control most of our lives. It is nearly as powerful as the Catholic Church once was

Believing in global warming has become a sign of virtue. Strange in a skeptical era. There is clearly a need for faith

Climate change is the religion of people who think they're too smart for religion

Some advice from the Buddha that the Green/Left would do well to think about: "Three things cannot be long hidden: The Sun, The Moon and The Truth"

Leftists have faith that warming will come back some day. And they mock Christians for believing in the second coming of Christ! They obviously need religion

Global warming has in fact been a religious doctrine for over a century. Even Charles Taze Russell, the founder of Jehovah's Witnesses, believed in it

A rosary for the church of global warming (Formerly the Catholic church): "Hail warming, full of grace, blessed art thou among climates and blessed is the fruit of thy womb panic"

Pope Francis is to the Catholic church what Obama is to America -- a mistake, a fool and a wrecker

Global warming is the predominant Leftist lie of the 21st century. No other lie is so influential. The runner up lie is: "Islam is a religion of peace". Both are rankly absurd.

"When it comes to alarmism, we’re all deniers; when it comes to climate change, none of us are" -- Dick Lindzen

The EPA does everything it can get away with to shaft America and Americans

Cromwell's famous plea: "I beseech you, in the bowels of Christ, think it possible you may be mistaken" was ignored by those to whom it was addressed -- to their great woe. Warmists too will not consider that they may be wrong ..... "Bowels" was a metaphor for compassion in those days

Inorganic Origin of Petroleum: "The theory of Inorganic Origin of Petroleum (synonyms: abiogenic, abiotic, abyssal, endogenous, juvenile, mineral, primordial) states that petroleum and natural gas was formed by non-biological processes deep in the Earth, crust and mantle. This contradicts the traditional view that the oil would be a "fossil fuel" produced by remnants of ancient organisms. Oil is a hydrocarbon mixture in which a major constituent is methane CH4 (a molecule composed of one carbon atom bonded to four hydrogen atoms). Occurrence of methane is common in Earth's interior and in space. The inorganic theory contrasts with the ideas that posit exhaustion of oil (Peak Oil), which assumes that the oil would be formed from biological processes and thus would occur only in small quantities and sets, tending to exhaust. Some oil drilling now goes 7 miles down, miles below any fossil layers

As the Italian chemist Primo Levi reflected in Auschwitz, carbon is ‘the only element that can bind itself in long stable chains without a great expense of energy, and for life on Earth (the only one we know so far) precisely long chains are required. Therefore carbon is the key element of living substance.’ The chemistry of carbon (2) gives it a unique versatility, not just in the artificial world, but also, and above all, in the animal, vegetable and – speak it loud! – human kingdoms.

David Archibald: "The more carbon dioxide we can put into the atmosphere, the better life on Earth will be for human beings and all other living things."

WISDOM:

"It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong." --- Richard P. Feynman.
Consensus is invoked only in situations where the science is not solid enough - Michael Crichton

"Science is the belief in the ignorance of the experts" – Richard Feynman

"The desire to save humanity is always a false front for the urge to rule it" -- H L Mencken

'Nothing is more terrible than ignorance in action' -- Goethe

“Doubt is not a pleasant condition, but certainty is absurd.” -- Voltaire

Lord Salisbury: "No lesson seems to be so deeply inculcated by experience of life as that you should never trust experts. If you believe doctors, nothing is wholesome; if you believe theologians, nothing is innocent; if you believe soldiers, nothing is safe."

Calvin Coolidge said, "If you see 10 troubles coming down the road, you can be sure that nine will run into the ditch before they reach you." He could have been talking about Warmists.

Some advice from long ago for Warmists: "If ifs and ans were pots and pans,there'd be no room for tinkers". It's a nursery rhyme harking back to Middle English times when "an" could mean "if". Tinkers were semi-skilled itinerant workers who fixed holes and handles in pots and pans -- which were valuable household items for most of our history. Warmists are very big on "ifs", mays", "might" etc. But all sorts of things "may" happen, including global cooling

Bertrand Russell knew about consensus: "The fact that an opinion has been widely held is no evidence whatever that it is not utterly absurd; indeed in view of the silliness of the majority of mankind, a widespread belief is more likely to be foolish than sensible.”

There goes another beautiful theory about to be murdered by a brutal gang of facts. - Duc de La Rochefoucauld, French writer and moralist (1613-1680)

"Pluralitas non est ponenda sine necessitate" -- William of Occam

Was Paracelsus a 16th century libertarian? His motto was: "Alterius non sit qui suus esse potest" which means "Let no man belong to another who can belong to himself." He was certainly a rebel in his rejection of authority and his reliance on observable facts and is as such one of the founders of modern medicine

"In science, refuting an accepted belief is celebrated as an advance in knowledge; in religion it is condemned as heresy". (Bob Parks, Physics, U of Maryland). No prizes for guessing how global warming skepticism is normally responded to.

"Almost all professors of the arts and sciences are egregiously conceited, and derive their happiness from their conceit" -- Erasmus

"The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, scepticism is the highest of duties; blind faith the one unpardonable sin." -- Thomas H. Huxley

Time was, people warning the world "Repent - the end is nigh!" were snickered at as fruitcakes. Now they own the media and run the schools.

"One of the sources of the Fascist movement is the desire to avoid a too-rational and too-comfortable world" -- George Orwell, 1943 in Can Socialists Be Happy?

The whole problem with the world is that fools and fanatics are always so certain of themselves, but wiser people so full of doubts -- Bertrand Russell

“Affordable energy in ample quantities is the lifeblood of the industrial societies and a prerequisite for the economic development of the others.” -- John P. Holdren, Science Adviser to President Obama. Published in Science 9 February 2001

The closer science looks at the real world processes involved in climate regulation the more absurd the IPCC's computer driven fairy tale appears. Instead of blithely modeling climate based on hunches and suppositions, climate scientists would be better off abandoning their ivory towers and actually measuring what happens in the real world.' -- Doug L Hoffman

Something no Warmist could take on board: "Knuth once warned a correspondent, "Beware of bugs in the above code; I have only proved it correct, not tried it." -- Prof. Donald Knuth, whom some regard as the world's smartest man

"To be green is to be irrational, misanthropic and morally defective. They are the barbarians at the gate we have to stand against" -- Rich Kozlovich

“We’ve got to ride this global warming issue. Even if the theory of global warming is wrong, we will be doing the right thing in terms of economic and environmental policy.“ – Timothy Wirth,
President of the UN Foundation

“Isn’t the only hope for the planet that the industrialized civilizations collapse? Isn’t it our responsibility to bring that about?” – Maurice Strong, founder of the UN Environment Programme (UNEP)

Leftists generally and Warmists in particular very commonly ascribe disagreement with their ideas to their opponent being "in the pay" of someone else, usually "Big Oil", without troubling themselves to provide any proof of that assertion. They are so certain that they are right that that seems to be the only reasonable explanation for opposition to them. They thus reveal themselves as the ultimate bigots -- people with fixed and rigid ideas.

ABOUT:

This is one of TWO skeptical blogs that I update daily. During my research career as a social scientist, I was appalled at how much writing in my field was scientifically lacking -- and I often said so in detail in the many academic journal articles I had published in that field. I eventually gave up social science research, however, because no data ever seemed to change the views of its practitioners. I hoped that such obtuseness was confined to the social scientists but now that I have shifted my attention to health related science and climate related science, I find the same impermeability to facts and logic. Hence this blog and my FOOD & HEALTH SKEPTIC blog. I may add that I did not come to either health or environmental research entirely without credentials. I had several academic papers published in both fields during my social science research career

Update: After 8 years of confronting the frankly childish standard of reasoning that pervades the medical journals, I have given up. I have put the blog into hibernation. In extreme cases I may put up here some of the more egregious examples of medical "wisdom" that I encounter. Greenies and food freaks seem to be largely coterminous. My regular bacon & egg breakfasts would certainly offend both -- if only because of the resultant methane output

Since my academic background is in the social sciences, it is reasonable to ask what a social scientist is doing talking about global warming. My view is that my expertise is the most relevant of all. It seems clear to me from what you will see on this blog that belief in global warming is very poorly explained by history, chemistry, physics or statistics.

Warmism is prophecy, not science. Science cannot foretell the future. Science can make very accurate predictions based on known regularities in nature (e.g. predicting the orbits of the inner planets) but Warmism is the exact opposite of that. It predicts a DEPARTURE from the known regularities of nature. If we go by the regularities of nature, we are on the brink of an ice age.

And from a philosophy of science viewpoint, far from being "the science", Warmism is not even an attempt at a factual statement, let alone being science. It is not a meaningful statement about the world. Why? Because it is unfalsifiable -- making it a religious, not a scientific statement. To be a scientific statement, there would have to be some conceivable event that disproved it -- but there appears to be none. ANY event is hailed by Warmists as proving their contentions. Only if Warmists were able to specify some fact or event that would disprove their theory would it have any claim to being a scientific statement. So the explanation for Warmist beliefs has to be primarily a psychological and political one -- which makes it my field

And, after all, Al Gore's academic qualifications are in social science also -- albeit very pissant qualifications.

A "geriatric" revolt: The scientists who reject Warmism tend to be OLD! Your present blogger is one of those. There are tremendous pressures to conformity in academe and the generally Leftist orientation of academe tends to pressure everyone within it to agree to ideas that suit the Left. And Warmism is certainly one of those ideas. So old guys are the only ones who can AFFORD to declare the Warmists to be unclothed. They either have their careers well-established (with tenure) or have reached financial independence (retirement) and so can afford to call it like they see it. In general, seniors in society today are not remotely as helpful to younger people as they once were. But their opposition to the Warmist hysteria will one day show that seniors are not completely irrelevant after all. Experience does count (we have seen many such hysterias in the past and we have a broader base of knowledge to call on) and our independence is certainly an enormous strength. Some of us are already dead. (Reid Bryson and John Daly are particularly mourned) and some of us are very senior indeed (e.g. Bill Gray and Vince Gray) but the revolt we have fostered is ever growing so we have not labored in vain.

Jimmy Carter Classic Quote from 1977: "Because we are now running out of gas and oil, we must prepare quickly for a third change, to strict conservation and to the use of coal and permanent renewable energy sources, like solar power.

SOME POINTS TO PONDER:

Today’s environmental movement is the current manifestation of the totalitarian impulse. It is ironic that the same people who condemn the black or brown shirts of the pre WW2 period are blind to the current manifestation simply because the shirts are green.

Climate is just the sum of weather. So if you cannot forecast the weather a month in advance, you will not be able to forecast the climate 50 years in advance. And official meteorologists such as Britain's Met Office and Australia's BOM, are very poor forecasters of weather. The Met office has in fact given up on making seasonal forecasts because they have so often got such forecasts embarrassingly wrong. Their global-warming-powered "models" just did not deliver

Hearing a Government Funded Scientist say let me tell you the truth, is like hearing a Used Car Salesman saying let me tell you the truth.

A strange Green/Left conceit: They seem to think (e.g. here) that no-one should spend money opposing them and that conservative donors must not support the election campaigns of Congressmen they agree with

David Brower, founder Sierra Club: “Childbearing should be a punishable crime against society, unless the parents hold a government license"

After three exceptionally cold winters in the Northern hemisphere, the Warmists are chanting: "Warming causes cold". Even if we give that a pass for logic, it still inspires the question: "Well, what are we worried about"? Cold is not going to melt the icecaps is it?"

It's a central (but unproven) assumption of the Warmist "models" that clouds cause warming. Odd that it seems to cool the temperature down when clouds appear overhead!

To make out that the essentially trivial warming of the last 150 years poses some sort of threat, Warmists postulate positive feedbacks that might cut in to make the warming accelerate in the near future. Amid their theories about feedbacks, however, they ignore the one feedback that is no theory: The reaction of plants to CO2. Plants gobble up CO2 and the more CO2 there is the more plants will flourish and hence gobble up yet more CO2. And the increasing crop yields of recent years show that plantlife is already flourishing more. The recent rise in CO2 will therefore soon be gobbled up and will no longer be around to bother anyone. Plants provide a huge NEGATIVE feedback in response to increases in atmospheric CO2

Every green plant around us is made out of carbon dioxide that the plant has grabbed out of the atmosphere. That the plant can get its carbon from such a trace gas is one of the miracles of life. It admittedly uses the huge power of the sun to accomplish such a vast filtrative task but the fact that a dumb plant can harness the power of the sun so effectively is also a wonder. We live on a rather improbable planet. If a science fiction writer elsewhere in the universe described a world like ours he might well be ridiculed for making up such an implausible tale.

Greenies are the sand in the gears of modern civilization -- and they intend to be.

The Greenie message is entirely emotional and devoid of all logic. They say that polar ice will melt and cause a big sea-level rise. Yet 91% of the world's glacial ice is in Antarctica, where the average temperature is around minus 40 degrees Celsius. The melting point of ice is zero degrees. So for the ice to melt on any scale the Antarctic temperature would need to rise by around 40 degrees, which NOBODY is predicting. The median Greenie prediction is about 4 degrees. So where is the huge sea level rise going to come from? Mars? And the North polar area is mostly sea ice and melting sea ice does not raise the sea level at all. Yet Warmists constantly hail any sign of Arctic melting. That the melting of floating ice does not raise the water level is known as Archimedes' principle. Archimedes demonstrated it around 2,500 years ago. That Warmists have not yet caught up with that must be just about the most inspissated ignorance imaginable. The whole Warmist scare defies the most basic physics. Yet at the opening of 2011 we find the following unashamed lying by James Hansen: "We will lose all the ice in the polar ice cap in a couple of decades". Sadly, what the Vulgate says in John 1:5 is still only very partially true: "Lux in tenebris lucet". There is still much darkness in the minds of men.

The repeated refusal of Warmist "scientists" to make their raw data available to critics is such a breach of scientific protocol that it amounts to a confession in itself. Note, for instance Phil Jones' Feb 21, 2005 response to Warwick Hughes' request for his raw climate data: "We have 25 years or so invested in the work. Why should I make the data available to you, when your aim is to try and find something wrong with it?" Looking for things that might be wrong with a given conclusion is of course central to science. But Warmism cannot survive such scrutiny. So even after "Climategate", the secrecy goes on.

Most Greenie causes are at best distractions from real environmental concerns (such as land degradation) and are more motivated by a hatred of people than by any care for the environment

Global warming has taken the place of Communism as an absurdity that "liberals" will defend to the death regardless of the evidence showing its folly. Evidence never has mattered to real Leftists

‘Global warming’ has become the grand political narrative of the age, replacing Marxism as a dominant force for controlling liberty and human choices. -- Prof. P. Stott

The modern environmental movement arose out of the wreckage of the New Left. They call themselves Green because they're too yellow to admit they're really Reds. So Lenin's birthday was chosen to be the date of Earth Day. Even a moderate politician like Al Gore has been clear as to what is needed. In "Earth in the Balance", he wrote that saving the planet would require a "wrenching transformation of society".

For centuries there was a scientific consensus which said that fire was explained by the release of an invisible element called phlogiston. That theory is universally ridiculed today. Global warming is the new phlogiston. Though, now that we know how deliberate the hoax has been, it might be more accurate to call global warming the New Piltdown Man. The Piltdown hoax took 40 years to unwind. I wonder....

Motives: Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is generally to promote themselves as wiser and better than everyone else, truth regardless.

Policies: The only underlying theme that makes sense of all Greenie policies is hatred of people. Hatred of other people has been a Greenie theme from way back. In a report titled "The First Global Revolution" (1991, p. 104) published by the "Club of Rome", a Greenie panic outfit, we find the following statement: "In searching for a new enemy to unite us, we came up with the idea that pollution, the threat of global warming, water shortages, famine and the like would fit the bill.... All these dangers are caused by human intervention... The real enemy, then, is humanity itself." See here for many more examples of prominent Greenies saying how much and how furiously they hate you.

After fighting a 70 year war to destroy red communism we face another life-or-death struggle in the 21st century against green communism.

The conventional wisdom of the day is often spectacularly wrong. The most popular and successful opera of all time is undoubtedly "Carmen" by Georges Bizet. Yet it was much criticized when first performed and the unfortunate Bizet died believing that it was a flop. Similarly, when the most iconic piece of 20th century music was first performed in 1913-- Stravinsky's "Rite of Spring" -- half the audience walked out. Those of us who defy the conventional wisdom about climate are actually better off than that. Unlike Bizet and Stravinsky in 1913, we KNOW that we will eventually be vindicated -- because all that supports Warmism is a crumbling edifice of guesswork ("models").

Al Gore won a political prize for an alleged work of science. That rather speaks for itself, doesn't it?

Jim Hansen and his twin

Getting rich and famous through alarmism: Al Gore is well-known but note also James Hansen. He has for decades been a senior, presumably well-paid, employee at NASA. In 2001 he was the recipient of a $250,000 Heinz Award. In 2007 Time magazine designated him a Hero of the Environment. That same year he pocketed one-third of a $1 million Dan David Prize. In 2008, the American Association for the Advancement of Science presented him with its Scientific Freedom and Responsibility Award. In 2010 he landed a $100,000 Sophie Prize. He pulled in a total of $1.2 million in 2010. Not bad for a government bureaucrat.

See the original global Warmist in action here: "The icecaps are melting and all world is drowning to wash away the sin"

I am not a global warming skeptic nor am I a global warming denier. I am a global warming atheist. I don't believe one bit of it. That the earth's climate changes is undeniable. Only ignoramuses believe that climate stability is normal. But I see NO evidence to say that mankind has had anything to do with any of the changes observed -- and much evidence against that claim.

Seeing that we are all made of carbon, the time will come when people will look back on the carbon phobia of the early 21st century as too incredible to be believed

Meanwhile, however, let me venture a tentative prophecy. Prophecies are almost always wrong but here goes: Given the common hatred of carbon (Warmists) and salt (Food freaks) and given the fact that we are all made of carbon, salt, water and calcium (with a few additives), I am going to prophecy that at some time in the future a hatred of nitrogen will emerge. Why? Because most of the air that we breathe is nitrogen. We live at the bottom of a nitrogen sea. Logical to hate nitrogen? NO. But probable: Maybe. The Green/Left is mad enough. After all, nitrogen is a CHEMICAL -- and we can't have that!

The intellectual Roman Emperor Marcus Aurelius (AD 121-180) must have foreseen Global Warmism. He said: "The object in life is not to be on the side of the majority, but to escape finding oneself in the ranks of the insane."

The Holy Grail for most scientists is not truth but research grants. And the global warming scare has produced a huge downpour of money for research. Any mystery why so many scientists claim some belief in global warming?

For many people, global warming seems to have taken the place of "The Jews" -- a convenient but false explanation for any disliked event. Prof. Brignell has some examples.

Global warming skeptics are real party-poopers. It's so wonderful to believe that you have a mission to save the world.

There is an "ascetic instinct" (or perhaps a "survivalist instinct") in many people that causes them to delight in going without material comforts. Monasteries and nunneries were once full of such people -- with the Byzantine stylites perhaps the most striking example. Many Greenies (other than Al Gore and his Hollywood pals) have that instinct too but in the absence of strong orthodox religious committments they have to convince themselves that the world NEEDS them to live in an ascetic way. So their personal emotional needs lead them to press on us all a delusional belief that the planet needs "saving".

The claim that oil is a fossil fuel is another great myth and folly of the age. They are now finding oil at around seven MILES beneath the sea bed -- which is incomparably further down than any known fossil. The abiotic oil theory is not as yet well enough developed to generate useful predictions but that is also true of fossil fuel theory

Medieval Warm Period: Recent climatological data assembled from around the world using different proxies attest to the presence of both the MWP and the LIA in the following locations: the Sargasso Sea, West Africa, Kenya, Peru, Japan, Tasmania, South Africa, Idaho, Argentina, and California. These events were clearly world-wide and in most locations the peak temperatures during the MWP were higher than current temperatures.

Both radioactive and stable carbon isotopes show that the real atmospheric CO2 residence time (lifetime) is only about 5 years, and that the amount of fossil-fuel CO2 in the atmosphere is
maximum 4%.

Green/Left denial of the facts explained: "Rejection lies in this, that when the light came into the world men preferred darkness to light; preferred it, because their doings were evil. Anyone who acts shamefully hates the light, will not come into the light, for fear that his doings will be found out. Whereas the man whose life is true comes to the light" John 3:19-21 (Knox)

Against the long history of huge temperature variation in the earth's climate (ice ages etc.), the .6 of one degree average rise reported by the U.N. "experts" for the entire 20th century (a rise so small that you would not be able to detect such a difference personally without instruments) shows, if anything, that the 20th century was a time of exceptional temperature stability.

Recent NASA figures tell us that there was NO warming trend in the USA during the 20th century. If global warming is occurring, how come it forgot the USA?

Warmists say that the revised NASA figures do not matter because they cover only the USA -- and the rest of the world is warming nicely. But it is not. There has NEVER been any evidence that the Southern hemisphere is warming. See here. So the warming pattern sure is looking moth-eaten.

The latest scare is the possible effect of extra CO2 on the world’s oceans, because more CO2 lowers the pH of seawater. While it is claimed that this makes the water more acidic, this is misleading. Since seawater has a pH around 8.1, it will take an awful lot of CO2 it to even make the water neutral (pH=7), let alone acidic (pH less than 7).

In fact, ocean acidification is a scientific impossibility. Henry's Law mandates that warming oceans will outgas CO2 to the atmosphere (as the UN's own documents predict it will), making the oceans less acid. Also, more CO2 would increase calcification rates. No comprehensive, reliable measurement of worldwide oceanic acid/base balance has ever been carried out: therefore, there is no observational basis for the computer models' guess that acidification of 0.1 pH units has occurred in recent decades.

The chaos theory people have told us for years that the air movement from a single butterfly's wing in Brazil can cause an unforeseen change in our weather here. Now we are told that climate experts can "model" the input of zillions of such incalculable variables over periods of decades to accurately forecast global warming 50 years hence. Give us all a break!

Scientists have politics too -- sometimes extreme politics. Read this: "This crippling of individuals I consider the worst evil of capitalism... I am convinced there is only one way to eliminate these grave evils, namely through the establishment of a socialist economy, accompanied by an educational system which would be oriented toward social goals. In such an economy, the means of production are owned by society itself and are utilized in a planned fashion. A planned economy, which adjusts production to the needs of the community, would distribute the work to be done among all those able to work and would guarantee a livelihood to every man, woman, and child." -- Albert Einstein

The Lockwood & Froehlich paper was designed to rebut Durkin's "Great Global Warming Swindle" film. It is a rather confused paper -- acknowledging yet failing to account fully for the damping effect of the oceans, for instance -- but it is nonetheless valuable to climate atheists. The concession from a Greenie source that fluctuations in the output of the sun have driven climate change for all but the last 20 years (See the first sentence of the paper) really is invaluable. And the basic fact presented in the paper -- that solar output has in general been on the downturn in recent years -- is also amusing to see. Surely even a crazed Greenie mind must see that the sun's influence has not stopped and that reduced solar output will soon start COOLING the earth! Unprecedented July 2007 cold weather throughout the Southern hemisphere might even have been the first sign that the cooling is happening. And the fact that warming plateaued in 1998 is also a good sign that we are moving into a cooling phase. As is so often the case, the Greenies have got the danger exactly backwards. See my post of 7.14.07 and very detailed critiques here and here and here for more on the Lockwood paper and its weaknesses.

As the Greenies are now learning, even strong statistical correlations may disappear if a longer time series is used. A remarkable example from Sociology:"The modern literature on hate crimes began with a remarkable 1933 book by Arthur Raper titled The Tragedy of Lynching. Raper assembled data on the number of lynchings each year in the South and on the price of an acre’s yield of cotton. He calculated the correla­tion coefficient between the two series at –0.532. In other words, when the economy was doing well, the number of lynchings was lower.... In 2001, Donald Green, Laurence McFalls, and Jennifer Smith published a paper that demolished the alleged connection between economic condi­tions and lynchings in Raper’s data. Raper had the misfortune of stopping his anal­ysis in 1929. After the Great Depression hit, the price of cotton plummeted and economic condi­tions deteriorated, yet lynchings continued to fall. The correlation disappeared altogether when more years of data were added." So we must be sure to base our conclusions on ALL the data. In the Greenie case, the correlation between CO2 rise and global temperature rise stopped in 1998 -- but that could have been foreseen if measurements taken in the first half of the 20th century had been considered.

Greenie-approved sources of electricity (windmills and solar cells) require heavy government subsidies to be competitive with normal electricity generators so a Dutch word for Greenie power seems graphic to me: "subsidieslurpers" (subsidy gobblers)

Many newspaper articles are reproduced in full on this blog despite copyright claims attached to them. I believe that such reproductions here are protected by the "fair use" provisions of copyright law. Fair use is a legal doctrine that recognises that the monopoly rights protected by copyright laws are not absolute. The doctrine holds that, when someone uses a creative work in way that does not hurt the market for the original work and advances a public purpose - such as education or scholarship - it might be considered "fair" and not infringing.

There are also two blogspot blogs which record what I think are my main recent articles here and here. Similar content can be more conveniently accessed via my subject-indexed list of short articles here or here (I rarely write long articles these days)
